1 All patients were genotyped for allelic variants in genes encoding drug metabolizing enzymes (CYP3A4, CYP3A5, UGT1A1) and drug transporters (ABCB1, ABCC2 and ABCG2) that are involved in irinotecan disposition. Irinotecan ATP binding cassette subfamily B member 1 Homo sapiens
2 The C(max) of irinotecan was significantly lower in patients carrying the CC genotype at exon 26 of the ABCB1 gene compared with those harbouring at least one variant allele (P = 0.047). Irinotecan ATP binding cassette subfamily B member 1 Homo sapiens
3 CONCLUSIONS: The present exploratory study shows that genetic polymorphisms in drug transporter genes, particularly in ABCB1 and ABCG2 genes, may be important in influencing the pharmacokinetics of irinotecan and its metabolites. Irinotecan ATP binding cassette subfamily B member 1 Homo sapiens
4 The predictive value of the identified allelic variants in the ABCG2 and ABCB1 genes on irinotecan disposition should be further investigated in a larger patient population as well as in other ethnic populations. Irinotecan ATP binding cassette subfamily B member 1 Homo sapiens
